onsemi ECH8201-TL-H

Overview

ECH8201-TL-H from SANYO Semiconductor is an NPN epitaxial planar silicon transistor optimized for high-current switching applications, featuring V_CEO = 50 V, I_C = 10 A continuous, V_CE(sat) = 65–100 mV at I_C = 6 A / I_B = 300 mA, f_T = 230 MHz, and halogen-free compliance - deployed in IGBT/MOSFET gate drivers and motor control stages.

For engineers reviewing the ECH8201-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified saturation voltage under high-current drive, thermal dissipation on ceramic substrate (1.6 W), switching speed (t_on = 60 ns, t_f = 17 ns), and 8-pin surface-mount package configuration with triple-emitter layout.

Technical Context

The ECH8201-TL-H employs SANYO's FBET/MBIT process to achieve low V_CE(sat) and high current gain linearity across 500 mA–10 A range (h_FE = 560 typ. @ 500 mA; 110 min. @ 10 A). Its triple-emitter, quad-collector structure supports parallel current handling while minimizing thermal resistance in high-power switching nodes.

Designed for DC/DC converters and lamp/motor drivers, it operates with V_CB = 100 V, V_BE(sat) = 0.85–1.2 V at I_C = 5 A, and exhibits Cob = 60 pF at V_CB = 10 V - enabling stable high-frequency switching without excessive Miller feedback.

FAQ

What is the maximum continuous collector current rating for the ECH8201-TL-H?

The ECH8201-TL-H is rated for 10 A continuous collector current when mounted on a 900 mm² ceramic substrate with 0.8 mm thickness. This rating assumes T_a = 25°C and accounts for the device's thermal resistance in high-power switching configurations. Exceeding this current without adequate heat sinking risks junction temperature exceeding 150°C, triggering thermal shutdown or permanent degradation. The ECH8201-TL-H must be used within this limit to maintain reliability in motor driver or DC/DC converter designs.

Does the ECH8201-TL-H support high-frequency switching above 100 kHz?

Yes, the ECH8201-TL-H supports high-frequency switching up to at least 100 kHz due to its 230 MHz gain-bandwidth product (f_T) and fast switching times (t_on = 60 ns, t_f = 17 ns). These parameters enable clean signal integrity in hard-switched topologies like flyback and forward converters. The ECH8201-TL-H maintains sufficient current gain margin at 100 kHz, and its low Cob (60 pF) minimizes Miller-effect distortion - making it suitable for precision gate driving where timing fidelity is critical.

How many emitter and collector terminals does the ECH8201-TL-H have, and why?

The ECH8201-TL-H has three emitter terminals (pins 1–3) and four collector terminals (pins 5–8), implemented to reduce parasitic inductance and distribute current in high-di/dt applications. This multi-terminal layout lowers effective bond-wire inductance and improves thermal spreading across the die. In practice, the ECH8201-TL-H's triple-emitter structure enhances stability in IGBT gate drivers by suppressing oscillation during rapid turn-off - a key advantage over single-emitter alternatives.

Is the ECH8201-TL-H halogen-free and RoHS compliant?

Yes, the ECH8201-TL-H is halogen-free and complies with RoHS Directive 2011/65/EU. Its packaging and internal materials meet IEC 61249-2-21 requirements for halogen-free printed wiring boards and JEDEC J-STD-020 moisture sensitivity level (MSL) standards. This makes the ECH8201-TL-H suitable for environmentally regulated industrial and consumer electronics manufacturing where lead-free reflow and halogen-free assembly are mandatory.

What is the typical V_CE(sat) of the ECH8201-TL-H under standard operating conditions?

The typical V_CE(sat) of the ECH8201-TL-H is 65 mV at I_C = 6 A and I_B = 300 mA, with a maximum of 100 mV under the same conditions. This ultra-low saturation voltage directly reduces conduction losses - for example, yielding only 0.39 W loss at 6 A - which is critical for thermal management in compact motor drivers and lamp ballasts. The ECH8201-TL-H achieves this performance via SANYO's FBET/MBIT process and optimized epitaxial layer design.
